The rose family is a medium-sized family of flowering plants. The rose family (Rosaceae) is one of the major angiosperm families. The leaves are generally arranged spirally. Flowers of plants in the rose family are generally described as "showy". They are actinomorphic and almost always hermaphroditic. Rosaceae generally have five sepals, and five petals. They also have many spirally arranged stamens. The bases of the sepals, petals, and stamens are fused together to form a cup-like structure called a hypanthium. They can be arranged in racemes, spikes, or heads; solitary flowers are rare.
They are called a population, because they are the same species living in a given area. The word population means the amount of a certain species living in a certain environment.
summer would be colder or cooler for a bit, then drastically change and melt ice and raise sea levels, potentially ending the world. Winter would destroy crops because the cold would be too harsh for our ecosystem and would last a lot longer, about 6 months in fact!
